A spectrum (plural spectrum los yog spectrums) yog ib yam mob uas tsis txwv rau ib qho tshwj xeeb ntawm qhov tseem ceeb tab sis tuaj yeem sib txawv, tsis muaj cov kauj ruam, hla ib qho txuas ntxiv. Lo lus yog thawj zaug siv scientific hauv optics los piav txog zaj sawv ntawm cov xim nyob rau hauv pom lub teeb tom qab dhau los ntawm ib tug prism.
Tsuas yog li ntawd, dab tsi yog spectrum thiab nws hom?
Muaj peb hom ntawm spectrum uas ib yam khoom muaj peev xwm emit: nruam, emission thiab absorption spectrum . Cov piv txwv ntawm cov no hom ntawm spectrum qhia hauv qab no yog rau pom lub teeb raws li nws kis tawm ntawm ntshav mus rau liab, tab sis lub tswv yim yog tib yam rau txhua cheeb tsam ntawm lub electromagnetic spectrum.
Dab tsi yog meant los ntawm spectrum ntawm lub teeb? Lub teeb Spectrum . Lub teeb spectrum ua tau txhais tau tias qhov pom spectrum , qhov ntau ntawm wavelengths ntawm electromagnetic hluav taws xob uas peb ob lub qhov muag yog rhiab heev rau … los yog nws ua tau txhais tau tias ib zajlus (los yog daim duab lossis daim duab) ntawm qhov kev siv ntawm teeb vs nws wavelength (lossis, qee zaum, nws zaus).
Kuj nug, dab tsi yog spectrum thiab nws tsim li cas?
Ib qho emission spectrum yog kab qauv tsim thaum ib lub caij zoo siab thiab muab lub zog tawm. Ib qho nqus spectrum yog tsim thaum lub teeb dawb dhau los ntawm cov pa txias. Cov kab spectrum tsim los ntawm lub zog uas dhau los ntawm cov pa roj yog hu ua kev nqus spectrum.
Dab tsi yog qhov txawv ntawm spectrum thiab spectrum?
Emission Spectra VS Absorption Spectra Lub ntsiab qhov sib txawv ntawm emission thiab nqus spectrum yog qhov emission spectrum muaj cov kab sib txawv hauv spectrum hos ib absorption spectrum muaj cov kab xim tsaus hauv spectrum.

Ib qho piv txwv ntawm electromagnetic spectrum yog dab tsi?
Tag nrho cov electromagnetic spectrum, los ntawm qhov qis tshaj mus rau lub siab tshaj plaws zaus (ntev tshaj plaws mus rau luv tshaj wavelength), suav nrog tag nrho cov xov tooj cua tsis (xws li, xov tooj cua lag luam thiab TV, microwaves, radar), hluav taws xob infrared, pom lub teeb, ultraviolet hluav taws xob, X-rays, thiab gamma rays
Cov khoom muaj nqis spectrum yog dab tsi?
Kev txhais ntawm Spectrum Assets. Spectrum Assets txhais tau hais tias (i) tag nrho FCC Daim Ntawv Tso Cai Txoj Cai tuav los ntawm Cov Neeg Tawm Tswv Yim thiab lawv Cov Kev Txwv Tsis Pub Muaj Hnub Nyoog Hnub Nyoog thiab ib qho Kev Hloov Cov Khoom Muaj nqis raws li qhov ntawd thiab (ii) Peev Tshuag ntawm txhua qhov Spectrum Entity
Vim li cas qhov absorption spectrum rau chlorophyll a thiab qhov kev ua spectrum rau photosynthesis txawv?
Ib qho kev nqus spectrum qhia tag nrho cov xim ntawm lub teeb absorbed los ntawm cov nroj tsuag. Ib qho kev ua spectrum qhia tag nrho cov xim ntawm lub teeb uas siv hauv photosynthesis. Chlorophylls yog cov xim ntsuab uas nqus liab thiab xiav thiab koom nrog hauv photosynthesis ncaj qha
Dab tsi ntawm spectrum yog hnub ci?
Xws li lub spectrum los ntawm lub hnub yog lub npe hu ua 'pom spectrum', tab sis nws tsuas yog ib feem me me ntawm lub teeb nyob rau hauv lub electromagnetic spectrum, uas spans energies los ntawm xov tooj cua tsis mus rau gamma-rays. Lub spectrum ntawm lub hnub tshwm raws li ib tug tas mus li spectrum thiab yog nquag sawv cev raws li qhia hauv qab no
Dab tsi yog electromagnetic spectrum hauv psychology?
Electromagnetic spectrum. qhov ntau ntawm wavelengths ntawm electromagnetic hluav taws xob los ntawm gamma rays (yoj luv heev) mus rau xov tooj cua tsis (yoj ntev heev). Tib neeg lub qhov muag yog rhiab heev rau qhov nqaim ntawm wavelengths ntawm kwv yees li 400 txog 700 nm. Saib spectrum
